Two young orphans in the Tirolian Mountains come under siege by a vicious band of hunters. Frightened of being separated by child services following the death of their mother, a self-sufficient 16-year-old girl and her 10-year-old brother – who hasn’t spoken a word since seeing his father killed by the mayor – strive to live off the land in peace. Their innocence is shattered, however, when a group of hunters led by the mayor’s son brutalizes and rapes the free-spirited girl. Later, when a well-meaning social services worker arrives too late to protect the terrorized siblings, the girl and her brother prepare to take a stand against their ruthless attackers.

Two sisters and their boyfriends drive to a small cabin to spend the weekend with the girls parents. However, when they arrive, they find them missing and the cabin in disarray. Things worsen as they become stranded at the remote lake, cars not starting, cell phones useless. As the autumn sun fades away something creeps from its lake dwelling in search of blood… human blood. And while the mystery of what happened to the parents unravels so too does the bond of friendship as pasts crash in on the present. Not everyone will survive the night, but those that do will be dead in the water.
